(oi. cat-37) This invention relates to what may be terned a combinationdrain and pipe coupling and consists in-the provision of a pipe 0 i thischaracter especially but not necessarily limited to use in 5 connectionwith kitchen sinks.

Briefly, the invention seeks to simplify the construction of combinationdevices or this char acter and thereby materially reduce the cost or"both initially installing the drain and the subsequent repairingthereof.

Further, my improved construction increase the efficiency of the same tobe readily cleaned, and in shor inate the objectionable features of thetends to drain, permits the t, to elirnpresent day type of combinationdrain and pipe couplings.

The study of nection with the ace in- Figure 1 is an elevation inventionapplied to a invention will be best understood from a the followingdescription, taken in conoinpanying drawings, whereal view showing thekitchen sink.

Figure 2 is a plan view of the invention.

Figure 3 is a secti on the line 3-3 of Figure 4 is an elevational vional view taken substantially Figure 2.

ew of a tube or sleeve forming part of the invention.

Figure 5 is an end elevational view of a combined sleeve and nut.

Figure 6 is an e1 evational View of the. opposite end of the combinedsleeve and nut.

Figure '7 is a substantially on the Figure 8 is a side disc, and,

sectional view therethrough taken line '!-'l of Figure 6. elevationalview of a strainer Figure 9 is a bottom plan. view thereof.

With reference more in it will be seen that 1 designates generally acorn ventional kitchen sink, drain opening provided sink, and 4 thedepending opening.

The invention per ment thereof, consists of a tube V suitable lengthprovided at its with an outstanding 2 the drain trap, 3 the in thebottom of the surrounding said or sleeve 5 of uppermost end annularflange 6 adapted to seat within an annular groove '7 provided in thebottom of the sink said upper end the and presents a conical bead8 and ashoulder Below the shoulder 9 the sleeve or 1 about the opening 3. Atsleeve or tube 5 is thickened 9.

tube 5 is provided with a spiral thread 10. v

In actual practice, and as with the flange 6 groove '7, bead 8 is shownin Figure 8,

suitably seated within the disposed wholly within the detail to thedrawings;

se, in the preferred enibodiconfines of the flange 4, and interposedbetween the bea the like to provide a fluida packing of putty or tightjoint, the pack.-

d and the flange is ing being designated generally by the referencecharacter 11.

A nut l is provided on atively short sleeve edge turned inwar the upperend of a rel- 13 that at its free end has its dly as at 14 tosubstantially close the space between the peripheral wall of the sleeve13 and the tube threaded thereon. suitably provided with a lug when thenut is Internally, the sleeve 13 is 15 co-operable with.

the threads 18- for threading the nut 12 upwardly ina manner to clamp awasher or gasket 16 about the upper portion of the bead 5 between thenut 12 and the corresponding surfaces of shoulder 9 and flange 4.

With

in Figur scribed, and shown the packing 11 the parts applied as de e 3,it will be seen that of putty will be secured in the space between thebead 8 tube or and flange 4 between the flange 6 of the sleeve 5, andthe washer l6, clamped in position as just stated.

As shown in Figure 1, the sleeve 5 will be of such a into on othermethod length as to have its lower end telescope e end of the trap 2,and caulking or any way be resorted to to insure a water-tight jointbetween the trap end and sleeve 5. There is also provided a strainer,which as shown in Figure 8 c body 1'? of ornprises a concave disc-likemetal or other suitable material and suitably perforated to permit thepassage of water thcrethrough. The body provide 1'7 of the strainer is don its underside with aresilient anchor consisting of a plurality ofangularly related spring arms 18 suitably convex At their free ends thearms ly as at enable side oi the strainer.

18 are bent inward- 18a to provide fingers so related as to them toserve the purpose oi the spider now employed-in sink drains and usuallylocated the drain below the strainer. In use, and as clearly shown inFigure 3, the body 1'. of

the strainer is arranged within the upper end of the tube or sleeve 5,an annular seat 19 being provided for end of disposed with the strainerat'said upper the tube or sleeve 5. The strainer 17 is its concave sideupward, and with the spring arms 18 extending downwardly andfrictionally engaging sleeve 5, it

bowed contact the interior of the tube or being noted that the arms 18are outwardly to insure yieldable frictional with the body of the sleeve5.

To-facilitate both the positioning of, and the removal of the strainer17, there is provided a secured at one end to the suitable knob 20 whichlies wholly Within the cavity of the strainer.

From the above it will be apparent that I have provided a combinationstrainer and pipe coupling which consists of comparatively few parts,can be readily and easily installed, and which can repaired and cleanedwith facility, and without requiring the services of an experiencedplumber.

Even though I have herein shown and described the preferred embodimentof the invention, it is to be understood that the same is susceptible offurther changes, modifications and improvements coming within the scopeof the appended claims.

i claim:

1. A drain for sinks and the like comprising elongated tubular memberhaving an upper end portion adapted to be positioned within a drainopening formed in the bottom of the sink, and provided at said upper endwith a flange to engage the sink bottom, and an external conical beadfitting within the depending flange usually surroundi' the drainopening; said tubular member below said bead being also provided with aspiral thread, a nut member on the tubular member coacting with saidflange to secure the tubular member in place, and having a skirt portionto conceal the spiral thread when the nut member is in clamping positionrelative to the flange, a lug on the inside of the skirt coacting withthe thread to screw the nut home; said skirt portion having its free endcontracted to snugly fit about the tubular member 2. A drain and pipecoupling assembly for a sink having a drain opening in the bottomthereof together with a depending flange surrounding the opening; saidassembly including a tubular member having an upper end adapted to bepositioned in the drain opening and the lower end adapted to beconnected with a waste pipe, a bead on the upper end of said tubularmember adapted to be positioned within and spaced relative to saidflange to provide a space for a sealing agent, a flange on the upper endof the tubular member and resting on the sink bottom for closing theupper end of sale space, a gasket disposed about the tubular member toengage the lower ends of the bead and flange and close said space at thelower end of the latter, and a nut member threaded on the tubular mem erfor clamping the latter and the gasket in place.
